Decimal= 1.30

Percent = 65%

There is one whole block. And there are 3 rows on the second block out of 1 whole block. So 1 whole block plus 3 rows out of 10 rows is 1.3 and 65% percent out of 2 whole blocks or 100%.

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
